public interface RuleSet

Public interface defining a shorthand means of configuring a complete set of related Rule definitions, possibly associated with a particular namespace URI, in one operation. To use an instance of a class that imlements this interface:

• Create a concrete implementation of this interface.
• Optionally, you can configure a RuleSet to be relevant only for a particular namespace URI by configuring the value to be returned by getNamespaceURI().
• As you are configuring your Digester instance, call digester.addRuleSet() and pass the RuleSet instance.
• Digester will call the addRuleInstances() method of your RuleSet to configure the necessary rules.

getNamespaceURI

java.lang.String getNamespaceURI()

Return the namespace URI that will be applied to all Rule instances created from this RuleSet.

addRuleInstances

void addRuleInstances(Digester digester)

Add the set of Rule instances defined in this RuleSet to the specified Digester instance, associating them with our namespace URI (if any). This method should only be called by a Digester instance.

Parameters:

digester - Digester instance to which the new Rule instances should be added.
